Start with the control layout, not the wiring
The KEPLER 3G mixed switch puts one toggle and two dimmers on a single plate. Before you touch any wiring, decide which light the toggle will control and which two lights need dimming. A toggle is best for a light you simply switch on and off—a hallway, utility room, or outdoor light. Dimmers suit rooms where you adjust brightness: living areas, bedrooms, or dining spaces.
This planning step matters because the KEPLER plate is fully modular. You can combine toggles and dimmers across 1-, 2-, 3- and 4-gang plates, all finish-matched. If your layout changes later, you can rearrange the modules rather than replace the whole plate.
What the KEPLER 3G mixed switch includes
-
KEPLER 3G Paintable Mixed Switch 1Toggle/ 2Dimmer - Antique Brass: A 3-gang antique brass paintable mixed light switch combining 1 toggle and 2 dimmers on one plate, finish-matched to brass cabinet hardware. Confirms the exact configuration so you can match it to your room’s lighting plan before installation.
KEPLER 3G Paintable Mixed Switch 1Toggle/ 2Dimmer - Antique Brass
-
KEPLER 3G Paintable Mixed Switch 1Toggle/ 2Dimmer - Antique Brass: Toggle and dial are turned from solid brass in an antique brass finish, on a slim, flat, low-profile plate. The low-profile plate sits close to the wall, which affects how you prepare the wall surface if you plan to paint the plate.
-
KEPLER 3G Paintable Mixed Switch 1Toggle/ 2Dimmer - Antique Brass: The dimmer uses auto-detect leading or trailing edge dimming for smooth, flicker-free control with modern LEDs. You do not need to manually select a dimming mode; the module detects the load type, simplifying setup.
A safe order for fitting the switch
The supplied information does not include a wiring diagram or terminal labels, so the steps below cover the physical fitting and preparation that the product record supports. For the electrical connections, follow the instructions that come with the switch or consult a qualified electrician.
- Isolate the circuit: Switch off the relevant circuit at the consumer unit and verify that the power is off before removing the old switch. This is standard safety practice, not a product-specific instruction.
- Prepare the wall box and plate: The KEPLER plate is slim and flat. Check that your wall box is deep enough for the dimmer modules and that the wall surface is clean and flat so the plate sits evenly. If you plan to paint the paintable plate, do this before final assembly.
- Connect the toggle and dimmers: The product record does not list terminal markings or a wiring sequence. Use the supplied instructions or a qualified electrician to connect the toggle to its light and each dimmer to its respective load. The dimmer’s auto-detect feature means you do not need to set a leading or trailing edge mode manually.
- Mount the plate and test: Fix the plate to the wall box, restore power, and test each control. The toggle should switch its light on and off; each dimmer should adjust brightness smoothly. If a dimmer flickers or behaves unexpectedly, check that the lamp is compatible with trailing-edge dimming—the auto-detect module is designed for modern LEDs but does not guarantee compatibility with every lamp.
Painting the paintable plate without spoiling the brass
The KEPLER plate is described as paintable, which means you can finish it to match your wall. The toggle and dial are solid brass in an antique brass finish, so you will need to mask them carefully before painting. Remove the toggle and dial if the modular design allows, or use painter’s tape to cover the brass components completely. The product record does not specify a recommended paint type or preparation method, so follow the paint manufacturer’s instructions for surface preparation and drying times.
The antique brass finish is brushed and lacquered to hold its tone and is backed by a 2-year guarantee. Avoid abrasive cleaners or solvents on the brass; a soft dry cloth is sufficient for normal dusting.
When one toggle and two dimmers makes sense
This configuration suits a room where you want a mix of simple switching and mood control. Here is how to decide if it fits your space.
- Choose one toggle and two dimmers if: You have three lighting circuits in one area and want independent control: for example, a toggle for a utility light and dimmers for a main light and an accent light.
- Choose all dimmers if: Every light in the room benefits from dimming, such as a living room with layered lighting. The modular KEPLER system lets you swap the toggle for a dimmer module later.
- Choose all toggles if: You prefer simple on/off control and do not need dimming, such as in a hallway or closet. The same plate family supports this.
What the supplied evidence does not cover
The product record for the KEPLER 3G mixed switch does not include a wiring diagram, terminal labels, or a step-by-step electrical installation guide. It also does not specify a minimum load, maximum load, or a list of compatible lamp types beyond the general auto-detect leading/trailing edge dimming feature. If you need these details, check the instructions included with the product or consult a qualified electrician. Do not guess at wiring connections or load limits.
The record also does not confirm whether the plate is supplied with screws or other fixings. Check the box contents before starting.
